Description

The present invention relates to polymers for moisturizers. More specifically, the present invention relates to a polymer for a moisturizer, which is useful for a moisturizer, a skin cosmetic, an external preparation for the skin, a hair cosmetic, and the like.

Cosmetics contain moisturizers to prevent the skin from drying out. As conventional moisturizers, polyhydric alcohols such as glycerin and 1,3-butanediol, and sodium hyaluronate are known.

As a conventional moisturizer, a film-forming polymer-type moisturizer that suppresses the evaporation of water by forming a film on the skin surface by the polymer has also been proposed. For example, a hydrophilic polymer having a specific unit structure containing an amide group (Patent Document 1), having a specific structural unit, having a weight average molecular weight (Mw) of 5,000 to 150,000, and having a temperature of 30. A water-soluble (meth) acrylamide polymer for cosmetics or skin external preparations, which has a mass loss rate of 25% by mass or less after being left for 6 hours in a 50% by mass aqueous solution of the polymer at ° C. and 60% relative humidity (Patent Document 2). , 0.001% by mass to 0.02% by mass of an amphoteric polymer compound (A) composed of a polymer containing vinylpyrrolidone as a constituent unit and a biwa leaf extract (B) as an extract pure content (B'). And soybean extract (C) (pure extract (C')), and the content mass ratio represented by (A) / [(B') + (C')] is 1 to 1000. Fees (Patent Document 3) have been proposed.

However, conventional polyhydric alcohols such as glycerin and 1,3-butanediol have insufficient hygroscopicity under low humidity, cannot sufficiently maintain moisturizing property, and further have hygroscopicity under high humidity. There is a problem that stickiness occurs because it is too expensive. Further, there is a problem that the conventional Na hyaluronate is very expensive, and there is a problem that the blending amount is limited because the whole system is thickened due to the ultrahigh molecular weight.

Further, the moisturizers described in Patent Document 1 and Patent Document 2 are poor in moisturizing property, and there is room for improvement in moisturizing property under low humidity. Further, the moisturizer described in Patent Document 3 is such that the moisturizing effect cannot be maintained unless the loquat leaf extract or soybean extract and the polymer type moisturizer are used in combination.

Recently, the applicant has studied various compounds having excellent moisturizing performance, and has a structural unit derived from an unsaturated polymer having a lactam structure and a structural unit derived from an unsaturated polymer having a specific functional group. Even when the polymer does not add other moisturizing ingredients, it exhibits excellent moisturizing performance by itself, is also excellent in maintaining moisturizing properties under low humidity, and this polymer can be produced at a lower cost than Na hyaluronate. It is reported that there is (Patent Document 4).

<Gel Permeation Chromatography (GPC)>
The weight average molecular weight (Mw) of the polymer was measured by GPC (gel permeation chromatography). The measurement conditions, equipment, etc. are as follows.
Equipment: Tosoh EcoSEC HLC-8320GPC
Detector: Differential Refractometer (RI) Detector Column: SHODEX Asahipak GF-1G-7B, GF-310-HQ, GF-710-HQ
Column temperature: 40 ° C
Flow velocity: 0.5 mL / min
Injection volume: 10 μL (sample concentration 0.4 wt% eluent preparation solution)
Calibration curve: Polyethylene glycol GPC software manufactured by GL Sciences: EcoSEC-WS manufactured by Tosoh Corporation
Eluent: 0.1M sodium acetate / acetonitrile = 70/30 (v / v)

<Analysis of monomer>
The analysis of the monomer was measured using liquid chromatography under the following conditions.
Equipment: Shiseido "NANOSPACESI-2"
Column: Shiseido "CAPCELLPAK C18 UG120"
Column temperature: 20 ° C
Flow velocity; 0.1 ml / min
Eluent: Methanol for LC (manufactured by Wako Pure Chemical Industries, Ltd.) / Ultrapure water = 1/24 (mass ratio), 0.4% by mass of sodium 1-heptane sulfonate added

<Evaluation of application feel (elasticity)>
Three evaluators evaluated the feeling of application (feeling of elasticity).
Drop one drop of the sample solution in a 5 mL eye drop bottle on the inside of the forearm, apply it with your index finger, apply the sample solution and spread it on the skin (aqueous solution state) to feel the application feel (elasticity) (film thickness) evaluated. The feeling of elasticity is the force (normal stress) that acts upward with respect to the left and right movement of the finger when it is applied to the skin, and is also called the feeling of film thickness as an expression. It is preferable that a feeling of elasticity exists. The evaluation was made in 11 stages, and the larger the number, the stronger it was, and it was decided through discussions with three evaluators.
The evaluation of the main moisturizers is as follows.
10 points: High molecular weight hyaluronic acid (manufactured by Kikkoman, trade name "FCH-200") 0.5% aqueous solution 3 points: pure water, glycerin 27% aqueous solution, sucrose 30% aqueous solution

<Evaluation of residual feel (friction / adhesive)>
Three evaluators evaluated the coating feel (friction / adhesion).
Drop one drop of the sample solution in a 5 mL eye drop bottle on the inside of the forearm, apply it with your index finger, and when you have completely applied it (water evaporation state), you will feel it when you touch the surface to which the solution has been applied. "Friction" (squeaky and smooth feeling) and "adhesiveness" (sticky and moist feeling) were evaluated. The frictional feeling is a force (dynamic frictional force) that acts in the opposite direction to the left and right movement of the finger, and when there is no frictional feeling, it becomes a smooth feeling, which is preferable. The sticky feeling is a force that acts downward against an upward force that pulls a finger away from the skin (peeling resistance), and is expressed as sticky, sticky, moist, or the like. Generally, when the stickiness is strong, it shows an unpleasant stickiness, and when it is weak and moderate, it shows a good moist feeling. The evaluation was made on a scale of 10, with the larger the value being stronger, and the decision was made through discussions among the three evaluators.
The evaluation of the main moisturizers is as follows.
10 points: 30% aqueous solution of sucrose 8 points: 16% aqueous solution of sucrose 4 points: 27% aqueous solution of glycerin 3 points: pure water (no application is applied)
Regarding the numerical value of the adhesiveness evaluation of the residual feel, 1 to 4 are in the range where the adhesiveness is too weak, 5 to 7 are preferable in the range where the adhesiveness is weak and moderate, and 8 to 10 are strong and unpleasant stickiness. It is the range to be done. The frictional feeling of the residual feeling was evaluated only for the samples (corresponding to the adhesive feelings 5 to 7) having a preferable adhesiveness in the evaluation of the adhesive feeling of the residual feeling.

<Evaluation of moisturizing property>
The moisturizing property was evaluated by measuring the conductance of the subject's stratum corneum water content using SKICON-200EX under the following conditions.
Equipment: SKICON-200EX (manufactured by IBS)
Measurement environment: temperature 25 ° C, humidity 30%
The inside of the subject's forearm was washed to remove excess dirt and sebum. After 15 minutes, 50 μL of sample solution was applied to 8 cm ² . After 5 minutes, the conductance was measured from above the coating film using SKICON-200EX. After 1 hour and 2 hours, 50 μL of the sample solution was reapplied to 8 cm ^2, and after 3 hours, the conductance was measured again from above the coating film.
